When you realise.

It is never until the moment you can’t have something, that you realise how precious it was.

It is never until you have lost something, that you have an epiphany and realise what an idiot you were for not treasuring it.

It is never until you have been denied something, that you realise how much you really want it.

When you realise how big a fool you were, it’s probably already too late.
